목적: Recently, we have reported on the relationship between the threshold at 3 kHz and average of thresholds at 2 kHz and 4 kHz to obtain statistical evidence for the guidelines from the AAO–HNS Committee on Hearing and Equilibrium (1995). In the course of the research, we have questioned which of 2 kHz and 4 kHz is more likely to affect the 3 kHz. We have extended this concept and tried to measure 'logarithmic distances of hearing frequencies' which indicates the magnitude of interaction among frequencies measured in KNHANES 2010-2012 survey. 방법:We have evaluated how a certain frequency was influenced by the other frequencies with multiple linear regression analyses using each frequency (500, 1k, 2k, 3k, 4k, and 6k Hz) as a dependent variable and the other five frequencies independent variables. R 3.2.2 was used as the statistical program. 결과:As expected results, the influence of adjacent frequencies was strongest at all frequencies. The relative values of the correlation coefficients and logarithmic plots for frequencies(Hz) showed a linear relationship. The 1 kHz and 2 kHz have almost as much effect on the adjacent frequency as logarithmic distance of hearing frequency. The effect of 1 kHz on 500 Hz was stronger than expected and so was the effect of 3 kHz on 4 kHz. The effect of 2 kHz and 4 kHz on 3 kHz was estimated to have a smaller effect than expected. 결론:The clinical significance of logarithmic distance of hearing frequency would be reviewed.
